CAR-V-WHEEL.

SEEGIFIQATION forming part bf Letters Patent No. 707,120, dated August 19, 1902.

' Application filed August 30, 1901. $erial No. 73,888. '(No'modeL) To all whom it mag concern.-

Be it known that I,- GEORGE KILLIAN,-a citizen of the United States, and a resident of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvementsin Oar-Wheels, of which the following is a'complete specification, reference being made to the'accom-' panying drawings, forming a part thereof, in

which like figures of reference indicate like parts.

The object-of this invention istoprovide a car-wheel which shall combine the maximum of strength and lightnessand in which the tire shall be detachable and at the same time hereinafter set forth; and the invention consists in certain novel features of construction hereinafter described and claimed. V

In the drawings annexed, Figure Us a side elevation of a car-wheelconstructed according to my invention. Fig, 2 is a vertical sectional view thereof, taken on the line A A; and Fig. 3 is a detail sectional view,enlarged, of the tire and the adjacent parts of the body of the Wheel.

Referring to the drawings by reference-nu morals, 1 and 2 represent, respectively, the in-v ner and outer sections of the wheel-body; 3, the tire; 4, the axle, and 5 the bolts connecting the tire to the wheel-body. The bodysections are disks which abut againsteach other at their adjacent faces and whichare held closely together by being fitted tightly on the axle. The inner edges of their peripheries are grooved to receive between them. an

inwardly-extending annular flange 6, formed onthe tire about midway between its, inner. and its outer edges, said flange 6 being provided Withan annular subflange 7 on its in ner side and also on its outer side. The innor face of the tire portion proper on each side of the flange 6 fits against and covers the respective peripheries of the body disks or plates, and at intervals bolts 5 are passed through the two disks and "the flanges 6 and 7 to clamp the tire to the wheel, although it is probable that these bolts are not absolutely necessary to hold the tirein place'in view of the rigid connection of the hubs of the bodyplates to the axle.

It will be observed that the inner one of the subflanges 7 is nearer to the center of the wheel than the outer subflange. The object of this is to permit the innerdisk to be made smaller in diameterthanthe outer diskand'the inner edge of the tire adjacent to the. rail-flange correspondingly thickerywhereby the tire willbe-rendered stronger at the point where the greatest strain and wear come-namely,

where it bears upon the top of the rail.

It is obvious that I am not confined strictly to the exact construction shown and. de-

What I claim, and'desire to obtain by Letters Patent,"is-- Y I 1. A car-wheel, comprisedof two separate body-disksjthe innerfonebeingsmaller in di ameterthan the 'outer one,-a-tire provided v with an inward-extending'flangeclamped between the adjacentedges of said plates or 7 disks, saidplates or disks being grooved for the reception of said flange, and said tire bearing upon the peripheries of said disks and having the portion bearing on the inner disk thicker than the portion bearing on the outer disk, for the purposes set forth.

2. A car-wheel, consisting of a pair of separate disks, one being smaller in diameter than the other, and a'tire bearing upon and covering the peripheries of said disks and provided with an-inwjrd-extending flange having lateral subfianges,1the inner subflange being nearerthe center of the wheel and the inher part of the tire bearing on the inner disk being thicker than the outer for the} purposes set forth.

3. 'A'car wh'e'el consisting of a pair of sepapart of the tire,

rate body disks the inner one being smaller 1 in diameter than the outer one, and a tire bearing upon and coveringthe peripheries of said disks, the portion of the tire bearing on theinner'body-disk being asmuch thicker outer disk is greater in diameter than the inner disk, andmeans for attaching said tire to said plates.

In testimony whereof I have hereunto set 'than the part bearing on the outer disk as the I my name, in the presence of two -subscr ibing- Witnesses, this 22d day'ofAugust,'l90l I GEORGE KIL-L IANQ Witnesses: I
